Issue Summary

If a customer decides to migrate Confluence without users & groups, but the group names in the cloud are in upper case, it will break the relation between them, space permissions will not work properly.

Note: Confluence Server only allows group names in lower case.

Steps to Reproduce

1. Create a group in Confluence Server all in lower case.
2. Create the same group in the Cloud in upper case.
3. Insert this group into a space permission grid.
4. Migrate to the Cloud without users and groups.

Expected Results

The group membership will be case insensitive.

Actual Results

Group membership will be broken.

Workaround

Create the group in the Cloud with the exact same casing as in the Server.
